The undrilled shank (indicated by the 'A' suffix) pairs with self-locking nuts, eliminating the need for safety wire in many installations. Commonly used for control linkage attachment and airframe assembly.
Installation requires correct grip length selection with one thread protruding beyond the nut. Torque and safety procedures follow FAA AC 43.13-1B standards and the applicable aircraft maintenance manual.
